developed a route for the stereoselective synthesis of 1-oxa-2,2-(dimesityl)silacyclopentane acetals, intermediates in the synthesis of highly functionalized 1,3-diols. This route involves a diastereoselective conjugate addition reaction of a hydrosilyl anion, a subsequent diastereoselective enolate alkylation, and a fluoride-catalyzed intramolecular hydrosilylation reaction to afford the oxasilacyclopentane
我们已经开发了一种立体选择性合成 1-oxa-2,2-(二甲苯基)硅杂环戊烷缩醛的路线,该缩醛是合成高度官能化的 1,3-二醇的中间体。该路线涉及氢化硅烷基阴离子的非对映选择性共轭加成反应、随后的非对映选择性烯醇化物烷基化和氟化物催化的分子内氢化硅烷化反应以提供氧硅杂环戊烷缩醛。高度选择性的亲核取代反应,然后氧化 C-Si 键,生成所需的多元醇。
